Which thermometer should be used for oral or armpit temperature measurements?

1. Rectal thermometer

2. Digital thermometer

3. Glass thermometer

4. Oral thermometer

The correct answer is: Oral thermometer

The choice of thermometer for oral or armpit temperature measurements is significant because it ensures accuracy and comfort for the patient. An oral thermometer is specifically designed to measure temperature in the mouth and often includes features such as a shorter length or digital display that allows for quick readings. Using an oral thermometer for these measurements is appropriate because it is calibrated to provide reliable readings from the mouth or armpit, where temperature can vary from other body areas. This type of thermometer is also user-friendly, making it a preferred option in clinical settings for non-invasive temperature checks. In contrast, a rectal thermometer is intended for use in the rectum and may not provide an accurate reading when used in the mouth or armpit. Although digital thermometers and glass thermometers can sometimes be used for oral temperatures, the specific designation of an oral thermometer emphasizes its designed purpose for that method of measurement, which enhances the overall accuracy and effectiveness of the assessment.
